Singapore, one of the most densely populated islands in the world, boasts an excellent modern light-rail network. The system is run by Singapore Mass Rapid Transit (MRT), a company incorporated in August 1987, serving the city's major high-density travel corridors.THE PROJECT.Until late 1997, MRT was a basic network of four lines, giving a total route mileage of 83km (50 miles).he system is run by Singapore Mass Rapid Transit (MRT), a company incorporated in August 1987, serving the city's major high-density travel corridors.
The Sikora buffer method was designed to reproduce the same soil-buffer pH obtained with the SMP buffer method. Therefore, the Sikora buffer method is suited for the same type of soils intended for the SMP buffer method which includes silt loam that can contain appreciable extractable Al.
Add 5 mL of 0.5 M HCl to the 1:1 mixture of Sikora buffer and DI water. The pH of the solution should be 5.68Â±0.07. Procedure. Follow the procedure for making a 1:1 soil:water pH measurement (see Chapter X). Add a volume of Sikora buffer to the soil slurry that is equal to the volume of water used. For example, if 10 g of soil and 10 mL of DI water was used for soil pH, add 10 mL of Sikora buffer.
